WAREHOUSE-TRUCK.

SPECIFICATION formingpart of Letters Patent No. 771,804, dated October11, 1904.

Application filed April 18, 1904. Serial No. 203,608- (No model.)

To all whom it may concern:

Be it known that I, AUGUST E. R. BLoM UIs'r, a citizen of the UnitedStates, residing at Cleveland, in the county of Ouyahoga and State ofOhio, have invented certain new and useful Improvements inarehouse-Trucks; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to improvements in warehouse-trucks adapted toconvey boxes, barrels, and other bulky freight from one place toanother; and the object of the invention is to provide atruck which isadapted to mechanically raise the freight loaded thereon to such higherelevation in or through the truck as may be desired, so that the freightmay be unloaded upon a higher plane than that from which it was taken,all substantially asshown and described, and more particularly pointedout in the claims.

In the accompanying drawings, Figure 1 is a perspective front elevationof my new and improved truck; and Fig. 2 is a longitudinal sectionalelevation thereof, showing the lifting mechanism engaged upon a cask orbarrel.

A represents the main frame of the truck, which may be substantiallysimilar to warehouse-trucks ordinarily, and O is a carrier for thefreight slidably engaged in slots, grooves, or channels a in the sidesof the said main frame. The carrier O is of the skeleton pattern, ashere shown, and preferably of cast metal of the requisite size, butwhich may also be made of any other metal or material that will suit thepurpose, and is provided with ribs or projections 0 at its sides adaptedto slide in said grooves or channels a and to be raised in respect tothe said main frame according to the elevation at which a piece offreight is to be discharged from the truck. Upon the bottom of the saidcarrier are hooks c, spaced apart relatively as shown and in position toengage the chime bof a barrel D, as seen in Fig. 2, or the edge of abox, and for which purpose the said carrier O is lowered to make suchengagement before the barrel,-box, cask, or other article has beendelivered upon the yoke-shaped lift or support B at the bottom of thetruck. The said carrier C is more or less concaved or curved outcentrally in its middle portion to rest the barrel therein and avoidtendency to roll out at either side, and an adjustable hook g isprovided on the upper end of the forked hook-supporting member G, whichis pivoted at its two forked extremities or ends in cars or lugs c onthe carrier and has a threaded upper extremity g with a lock-nut g orthe like thereon over the hook g, whereby the said hook can be raised toa higher or lower point on the said stem g and is adapted to engage acask, barrel, or other article of larger or, smaller size, theproportions of adjustment accomplished in this respect being clearlyseen in Fig. 2. Power is applied to the said carrier O to raise the samewith the load thereon by means of a threaded shaft H, having engagementwith the upper portion of said carrier O through threaded sleeve 0thereon and carrying a bevel-gear /L at its upper end outside thecross-bar a of the main frame A, in which said shaft is supported. Apinion a on ashort transverse shaft N, through the side of frame A,engages the gear and is adapted to be operated by a hand-crank J, whichserves to apply power to the said shaft H and by the rotation thereofcauses the carrier O to be lifted more or less, as may be required.

A swinging and practically free brace M is provided at about the centerandbottom of the truck, which serves in one way and another to assist inthe handling of the truck and freight thereon,and especially serves tosteady or support the truck, as seen in Fig. 2, when the carrier isbeing raised with the load thereon.

By the means thus shown and described I am enabled to lift a piece offreight from the floor and deposit the same upon a platform or otherelevated position a foot or more above the floor-level with no moreexpenditure of strength than is expended through crank J, and this isvery slight compared with the weight lifted.

What I claim is- 1. A warehouse-truck having a slidable carrier confinedwithin its sides and provided with fixed hooks at its bottom andaswinging threaded arm at its top and a hook adjustable on said arm toengage the freight, and means to raise and lower the said carrier inrespect to the frame, substantially as described.

2. A warehouse-truck having guideways at its sides and a carrierslidable thereon, said carrier having rigid hooks at its bottom tosupport the freight and a pivotally-supported adjustable hook at its topto engage the top of the freight, and mechanism to raise said carrierwith the freight thereon, substantially as described.

3. A warehouse-truck having guideways in its sides, a carrier forfreight slidably supported in said guideways and provided with supportsat its bottom to carry the freight, and means at the top of said carrieradapted to engage the freight at its upper portion, said meanscomprising a forked hook-support pivoted on said carrier and a hook atright on said carrier to secure a piece of freight thereon,substantially as described.

In testimony whereof I sign this specification in the presence of twowitnesses.
